I am trying to develop a small proof-of-concept patch for a proposal I have, but recently I found that initdb started segfaulting after I did a git pull. I used git bisect and it identified the following commit as the first one with the problem:

1733460f0205fc6d6bbe4c14911049a918c6e073 is the first bad commit

commit 1733460f0205fc6d6bbe4c14911049a918c6e073

    postgres_fdw: Fourth attempt to stabilize regression tests.

    

    Commit 1bc0100d270e5bcc980a0629b8726a32a497e788 added this test, and

    commits 882ea509fe7a4711fe25463427a33262b873dfa1,

    958e20e42d6c346ab89f6c72e4262230161d1663,

    4fa396464e5fe238b7994535182f28318c61c78e tried to stabilize it.  It's

    still not stable, so keep trying.

    

    The latest comment from Tom Lane is that disabling autovacuum seems

    like a good strategy, but we might need to do it on more tables, hence

    this patch.

I'm not particularly confident I've done this right but if anybody else is having trouble with systems compiled from recent commits this might be a starting point to look at.

Incidentally I'm working on Mac OS X 10.11.6 in case that's helpful.

And I just looked at the commit and as far as I can tell it only affects tests, which shouldn't affect whether initdb segfaults, which makes me think I've done something wrong.

So is anybody else finding that initdb segfaults with a newly-compiled system?
